A new teacher is staying after school grading tests for her class. When she glances out the window, she sees a student in an unfamiliar, old-looking school uniform, laying white powder lines in the schoolyard. The teacher steps outside to issue a warning, but the student is gone, and the white line continues into the school building. So she follows it inside to find the student...
the only sound she heard was 
the line marker's wheels.
الصوت الوحيد الذي سمعته هو عجلات صانع الخط
hörte sie nur das Geräusch
des Markierwagen.
résonne dans le bâtiment désert.
la giovane sentiva solo il rumore delle ruote del traccialinee.
o único som que se ouvia 
era o das rodas do marcador.
